On 16 September 2026, ISO published the revised edition of the world’s most widely used management system standard. With the publication of ISO 9001:2026, the transition period begins for all organisations certified to ISO 9001:2015. The good news first: this is an evolution, not a fresh start. If you run a living quality management system, you do not have to start from scratch. But it will not happen without any work either.
What stays the same
The structure still follows the harmonised structure that ISO prescribes for all management system standards. Clauses 4 to 10 keep their order: context of the organisation, leadership, planning, support, operation, performance evaluation and improvement. The three core ideas also remain the foundation: the process approach, the plan-do-check-act cycle and risk-based thinking.
For organisations that already run ISO 27001, ISO 14001 or ISO 42001, this is a relief. Common building blocks such as context analysis, management review or internal audits can still be built and evidenced jointly for several systems.
What changes in substance
According to the summaries published by certification bodies, the changes mainly concern five points. We summarise them in our own words. The text of the standard is authoritative.
- Quality culture and ethical behaviour. The standard anchors more firmly the idea that quality is also a matter of attitude. This concerns leadership, employee awareness and the environment in which processes take place. For the audit, this means it is not enough for guidelines to exist. Management is expected to lead by example in what it demands.
- Risks and opportunities separated. Until now, both were often dealt with in one table. The new edition distinguishes more clearly and sets separate requirements for each. Many organisations will split their risk overview accordingly.
- Changes to the management system. The requirements for planning, communicating, monitoring and evaluating changes are sharpened. If you introduce new sites, products, systems or organisational forms, you should be able to show that the consequences for the QMS were considered.
- Terms directly in the standard. A small selection of key terms from the ISO 9000 family now appears directly in ISO 9001. This makes interpretation easier but does not change any obligations.
- More detailed Annex A. The informative annex explains the structure, terms and intent of individual requirements in more detail. It adds no obligations but helps with interpretation.
How long the transition lasts
The transition period is not set by ISO but by the international accreditation community. Certification bodies consistently communicate three years from publication, i.e. until 30 September 2029. Until then, a certificate to ISO 9001:2015 remains valid. After that, it expires or is withdrawn if the transition has not taken place.
That sounds like a lot of time. In practice, it is tighter than it seems. The transition is usually assessed as part of a regular surveillance or recertification audit. With a three-year certification cycle, you therefore only have a limited number of suitable audit dates. Experience shows that auditors are heavily booked in the last year of a transition period. If you wait until 2029, you risk not getting a date at all.
The exact procedure, the duration of the transition audit and any additional days are set by your certification body. Ask them early.
How to approach the transition
- Obtain the standard and record the differences. Compare the clauses of your existing system with the new edition. Note where you already comply, where you need to sharpen things and where something is missing.
- Make quality culture tangible. Think about how an auditor can tell that management and employees take quality seriously: objectives, communication, how mistakes are handled, involvement of employees.
- Separate risks and opportunities. Revise the risk overview so that both sides have their own assessments and actions.
- Review the change process. Is there a traceable way in which changes to the management system are planned and evaluated? If not, describe it briefly.
- Train and audit internally. Inform process owners and carry out an internal audit against the new edition before the external auditor arrives.
- Agree a date. Decide with your certification body in which audit the transition will take place.
What this means for you
If you are already certified, plan the transition into one of your next regular audits, ideally in 2027 or early 2028. Your certificate remains valid until then. If you are currently introducing a QMS, build it directly to ISO 9001:2026. A certificate to the old edition is hardly worthwhile now.
